SPECIFICATION forming part of Letters Patent No. 699,766, dated May 13,1902. Application filed August 26, 1901. Serial No. 73,386. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. ROBINSON, a citizen of the United States,residing at Port Huron, in the county of St. Clair and State ofMichigan, have invented certain new and useful Improvements iniVashing-lvlachines, of which the following is a specification,reference being had therein to the accompanying drawings.

The invention has reference generally to washing=machines; and itconsists in the novel construction of a machine of this type and in thepeculiar arrangement and combination of the various parts thereof, asmore fully hereinafter set forth.

In the drawings illustrating my invention, Figure l is a perspectiveview of the washingmachine. Fig. 2 is a vertical central section throughthe machine; and Fig. 3 is a sectional view of a portion of the machine,illustrating the construction of the springbacked packing for theguides.

In the drawings thus brieiiy described the reference-letter A designatesa supportingframe having a laterally-extendin g overhanging section I3,as shown. Mounted within this framework and suitably secured thereto isa suds-receptacle C, the main portion ofwhich is substantiallycylindrical in form. I'Vithin the receptacle and occupying the lowerhalf thereof is a rubbing-surface D.

E designates a cross-bar forming a part of the framework A, upon whichare mounted at each end thereof standards F, provided at their upperends with tubular bearings G. Journaled within the bearings described isa drive-shaft II, which is bent to form angularly-extending cranks I andcarries at one end a drive-wheel J.

K designates plunger rods extending through the cross-bar E of theframework and carrying at their lower ends pounders L, as plainly shownin Fig. 2. These pounders are preferably conical in configuration andare provided with a transverse apertured diaphragm M midway between theapex and base. The lower end of each rod extends within its respectivepounder, and the extreme end portion of the rod projects through thediaphragm, as indicated, the latter forming a brace for the rod whichgives rigidity to the pounder. The pounder-rods extend throughrectangular openings u, formed in the crossbar E, and are provided eachwith a stationary packing Z) for the rear edge and a springbackedpacking c for the forward edge or side of the rod. The latter packingsare carried by blocks O, which tit Within recessesV P, formed in theouter edge of the cross-bar, and are connected to the cross-bar by boltsQ, extending through said cross bar and clamped thereto by suitable nutsR. The springepacking, las shown, is adapted to fit within a recess CZ,formed in the inner edge of each block, and arranged intermediate therear portion of the packing and in the rear wall of the recess is acoiled spring e, which serves to keep the packing constantly in contactwith the plunger-rod, and thus take up the wear of the latter. The upperends of the plunger-rods are connected to their respective cranks uponthe shaft II by means of springs S, each spring laterally curved in theform of a gooseneck, as plainly shown in the drawings. The upper end ofeach spring is sleeved over the central portion of the crank, while thelower spring end extends within a slot formed in the top portion of thepounder-bar and is retained therein by suitL able bolts or screws f.

It will be obvious from the description of the machine as thu's setforth that upon rotating the drive-shaft through the agency of thehand-wheel .I an elliptical movement will be imparted to the pounders,and the latter will be caused to effectively act upon all of the clothesin the sinds-receptacle. The springs intermediate the pounder-rods andthe shaft admit of a yielding pressure upon the clothes. Thus the wearand tear on the clothes is reduced, and the jar of the machine caused bythe pounder striking the clothes is obviated. It is to be furthernoticed that the type of spring employed intermediate the pounderrodsand shaft is simple in construction, effective in operation, and may berigidly secured to the parts to be connected. Also in view of thesimplicity of the spring employed there are no parts to get out of orderand to require adjustment.

Vhat I claim as my invention is- In a washing-machine, the combinationwith the slide-receptacle, of a drive-shaft journaled in bearings abovesaid receptacle,
